Java- Stored Procedure with Call by Result

Hi Oracle-Community,
I am looking for some example Code how to use a Java-Stored Procedure with Out-Parameters. Don't get me wrong. I dont want to call a Procedure with Out Parameters from Java (there are a lot of examples for this out there) . I just want to implement the Call by Result concept in a Java-Stored Procedure. A Client will call this Procedure with some parameters and the Java Procedure will fill them. So my first question: is this possible? And my second Question: How to implement it?
Greetings.

I found out a solution. It is very simple.
Just defining the parameters as java array (e.g. String[] P1). The first value (P1[0]) is the returned value.
At last just set in JDeveloper in the "Edit Method Signature" Dialog the parametermode to OUT.
The dialog can be found by rightclicking on the stored procedure in the dbexport file. You can read this
in Section 6 Publishing Java Classes With Call Specifications -> Setting Parameter Modes in
Oracle Database Java Developer's Guide.

Is it possible to working in Java Stored Procedures with OCI driver?

Hello ALL.
Could you help me...
Is it possible to working in Java Stored Procedures with OCI driver?
I want to try to do some workaround...
I need to work with following parametrs from Java Stored Procedures:
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
String url = null;
url = "jdbc:oracle:oci:@TEST";
conn = DriverManager.getConnection (url,"scott","tiger");
Is it possible?
I tried but I have errors...
Please, help me!
Thanks

You cannot call OCI functions directly from PL/SQL. You could, of course, write an external procedure that made OCI calls, though you could also write an external procedure in Java. I'm guessing the documentation is trying to convey this same information-- you would need an external procedure that used OCI if you wanted to use the old-school interfaces for LONG and LOB data types. If you converted to using LOBs rather than LONGs, you could do everything in PL/SQL.

Java Stored Procedure with LOB as input parameter (oracle 9i 9.2.0.6)

Hi,
Is there a way to pass CLOB as input and output as part of java stored proceudre in oracle 9i (9.2.0.6)?
I have to perform some data conversion on the CLOB data in java program and return the converted CLOB as output.
--Ramesh Lokineni

The reason why I want to use java for conversion is because, I want to perform base64 encoding decoding on the content stored in CLOB column. I tried to use by chunking the data into smaller pieces and apply the base64 encoding, but when I decode the CLOB using base64, I am not getting the same data. Later when I read about how base64 encoding happens I realized chunking the data in CLOB doesn't work. That's when I started to diggin how I can pass CLOB to java stored procedures.

Java Stored Procedure SAXParser XML Schema Validation

Using Oracle XML Developers Kit 10.2.0.2.0 - Production.
Attempting to validate using XML Schema in a Java stored procedure with the code:
               if ( schemaDoc == null )
                    // Obtain default connection
                    Connection conn = new OracleDriver().defaultConnection();
                    OraclePreparedStatement stmt = (OraclePreparedStatement) conn.prepareStatement("SELECT XmlDocObj FROM XmlDoc WHERE XmlDocNbr = 2");
                    OracleResultSet rset = (OracleResultSet)stmt.executeQuery();
                    if ( rset.next() )
                         // get the XMLType
                         XMLType schemaXml = (XMLType)rset.getObject(1);
                         XSDBuilder builder = new XSDBuilder();
                         XMLSchema schemaDoc = (XMLSchema)builder.build(new InputSource(schemaXml.getInputStream()));
               if ( inst == null )
                    inst = new ValidateCoreRequest();
               ErrorHandlerImpl handler = inst.getNewErrorHandler();
SAXParser saxParser = new SAXParser();
saxParser.setXMLSchema(schemaDoc);
saxParser.setValidationMode(XMLParser.SCHEMA_VALIDATION);
saxParser.setErrorHandler(handler);
saxParser.parse(new InputSource(new StringReader(docStr)));
if( handler.validationError )
                    errorMsg[0] = handler.saxParseException.getMessage().substring(0, Math.min(199, handler.saxParseException.getMessage().length()));
Never reports validation errors in the XML. Although the XDK Programmers Guide states "...you can use
the oracle.xml.parser.schema.XSDBuilder class to build an XML schema and
then configure the parser to use it by invoking the XMLParser.setXMLSchema()
method. In this case, the XML parser automatically sets the validation mode to
SCHEMA_STRICT_VALIDATION and ignores the schemaLocation and
noNamespaceSchemaLocation attributes." No validation seems to occur. I have tried to set an xsi:noNamespaceSchemaLocation attribute on the root XML node, but this results in URL errors if the URL is not valid or schema build errors if the URL is valid, but does not point to a real location.
It appears that without a schema location attribute, no schema validation occurs. Using setXMLSchema() with a database source does not seem to cause the schema location attributes to be ignored. At least for Java stored procedures.
Does XML Schema validation work in the database for externally referenced schemas?
Thank You,
Art

Try this:
Edit your XSU installation script located on lib directory of Oracle XSU's distribution:
Find the line:
loadjava -r -v -u $USER_PASSWORD xmlparserv2.jar
Replace by:
loadjava -r -v -g public -u $USER_PASSWORD xmlparserv2.jar
And installs your Oracle XSU again.

Java stored procedure problem(oracle db)

HI,
we have a java stored procedure with the following definition, and that works as we want it to:
CREATE OR REPLACE FUNCTION processBulletin(in_varchar VARCHAR2) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(java.lang.String) return java.lang.String';
And the Java portion:
public static String processBulletin(String in_bull)
... do something with in_bull
The problem is that we've recently discovered that the 32767 size restiriction on the input parameter varchar2 is too small. I don't want to rewrite the entire Java procedure. I figured the simplest (or at least temporary)solution would be to have the Java procedure accept a CLOB, convert that clob to a string and continue as it would. I was hoping someone might be able to tell me if the following would be possible:
CREATE OR REPLACE FUNCTION processBulletin(in_clob CLOB) RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'JavaParser.Bufr_Ingest.processBulletin(oracle.sql.CLOB) return java.lang.String';
And the Java portion:
public static String processBulletin(oracle.sql.CLOB in_clob)
String in_bull = clob_in.getSubString(1, (int)clob_in.length());
... do something with in_bull
Thanks

I don't know about Java stored procedures, but in JDBC you usually use streams to work with CLOBS. Here's Oracle JDBC Developers Guide, Working with LOBs

Broken Java Stored Procedure Demo

The link to download HotelBookingsSample.jar does not work. It is located on http://otn.oracle.com/sample_code/tech/java/jsp/samples/jsptrigger/Readme.html

Do as follows:
Define a JDBC Connection to your DB - use this name only.
Create a Deployment profile (Java Stored Procedure )(with [x]Publish option) to the same connection.
Then in the deployment tab of the Message View (View | Message View), you will see the deployment.
Then you can call your procedures, functions using SQL*Plus by
Expand Connection Folder
Right Click on the JDBC Connection
Select Invoke SQL*Plus...
This will invoke SQL*Plus with the info from this connection.
In SQL*Plus enter various statements to invoke your Java Stored Procedure.
For grins, try:
In JDeveloper, select
File | New ... Class / JavaStoredProcedure
Add the following methods to the bottom:
=============
public static String getJDBTime( ) {
return (new Date()).toString();
private static int nSeq = 0;
public static int getNextSequence( ) {
return nSeq++;
===========
Then Create a deployment profile and deploy it.
Then Invoke SQL*Plus and call it as:
select <PackageName>.FunctionName() from dual;
In my case, my SQL*Plus window looked as:
SQL>
SQL>
SQL> select MYPROJECT5.GETJDBTIME() from dual;
MYPROJECT5.GETJDBTIME()
Wed Dec 20 16:12:16 CST 2000
SQL> select MYPROJECT5.GETJDBTIME() from dual;
MYPROJECT5.GETJDBTIME()
Wed Dec 20 16:12:22 CST 2000
SQL> select MYPROJECT5.GETNEXTSEQUENCE() from dual;
MYPROJECT5.GETNEXTSEQUENCE()
0
SQL> select MYPROJECT5.GETNEXTSEQUENCE() from dual;
MYPROJECT5.GETNEXTSEQUENCE()
1
SQL> select MYPROJECT5.GETNEXTSEQUENCE() from dual;
MYPROJECT5.GETNEXTSEQUENCE()

Deploy package with Java Stored Procedure without JDeveloper

I have a set of Java Stored Procedures deployed as a package on a Oracle 8i server. Everything works fine in my development environment, and now I would like to deploy the same package in the customers runtime environment. Both environments are running Oracle 8i rel 2 on NT.
Is there a simple way to use the JDeveloper .prf deployment profile without installing JDeveloper in the customers environment?
If not, can I the get the .jar files and .sql scripts from JDeveloper to create the call specs and package bodys?
I guess JDeveloper must have this information, and my idea was then to write a script using loadjava and SQL*Plus.
Regards,
Tom Bjerre

you would not be able to take just the deployment profile and run it outside JDeveloper.
You would be able to create archive of all java classes in the package using Deployment Wizard in JDeveloper.
Then you can load the jar file using the utilities in 8i.
JDeveloper does generate the SQL for CALL specs etc ., at the deployment time and it is printed in MEssage Viewer along with other information.
Hope that info is useful for you

APEX fails with Java stored procedure that creates a JDBC connection

Hello!
We are facing a strange problem since we have upgraded from Oracle 10g and Apache to Oracle 11g with Embedded Gateway.
Here is what we do:
** APEXX calls a PL/SQL package function "OPEN_CONNECTION" that wraps a Java stored procedure called "openConnection".*
FILE_READER_REMOTE_API.openConnection(user, password, host, port, service);
** The Java stored procedures "openConnection" opens a JDBC connection to an other database:*
public class FileReaderRemote {
private static Connection conn = null;
private static DefaultContext remoteContext = null;
public static void openConnection(String user, String password, String host, String port, String service) throws SQLException {
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
java.util.Properties props = new java.util.Properties();
props.put ("user", user);
props.put ("password", password);
//props.put ("database", "//" + host + ":" + port + "/" + service);
props.put ("database", host + ":" + port + ":" + service);
props.put("v$session.program", "FileReaderRemote2");
// Connect to the database
remoteContext = Oracle.getConnection("jdbc:oracle:thin:", props);
This procedure used to work fine before the upgrade, but now we see the following:
* It still works when called directly from TOAD or SQL*Plus, even under the user ANONYMOUS.
* When called from APEX and the target database is Oracle 11g, it still works.
* When called from APEX and the target database is Oracle 10g, it takes several minutes and we receive this error:
*"Socket read timed out"*
We have tested the following workaround:
We have created a database link to our own database and called the stored procedure through that database link.
FILE_READER_REMOTE_API.openConnection*@loopback*(user, password, host, port, service);
This works, but is not really an option.
I hope some one of you can explain this strange behaviour to me.
Best regards,
Matthias

You wrote
"Java stored procedures -- by definition - are stored in the 8i rdbms. !!"
From the Oracle8i Java Stored Procedures Developer's Guide
Release 8.1.5
A64686-01
"If you create Java class files on the client side, you can use loadjava to upload them into the RDBMS. Alternatively, you can upload Java source files and let the Aurora JVM compile them. In most cases, it is best to compile and debug programs on the client side, then upload the class files for final testing within the RDBMS"
This means that you can create shared classes that are used on both the client and server side. The source does not need to reside within the server (according to their documentation). Please also note the following from the Oracle8i JDBC Developer's Guide and Reference Release 8.1.5 A64685-01 for using the getConnection() method on the server:
"If you connect to the database with the DriverManager.getConnection() method, then use the connect string jdbc:oracle:kprb:. For example:
DriverManager.getConnection("jdbc:oracle:kprb:");
Note that you could include a user name and password in the string, but because you are connecting from the server, they would be ignored."
So if you're coding a shared class that is to run on both the client and server side, you might do something like this:
Connection conn =
DriverManager.getConnection(
System.getProperty("oracle.server.version") == null
? "jdbc:oracle:thin:@hostname:1521:ORCL"
: "jdbc:oracle:kprb:"),
"youruserid","yourpassword");
As stated earlier, the userid and password are supposedly ignored for server connections retrieved in this manner. I haven't tried this yet, but it is documented by Oracle.

Problems with java stored procedure.

I have a java stored procedure that uses a package called RmiJdbc
which allows calling remote JDBC data sources from any java capable
machine.
I've loaded the RmiJdbc classes into oracle via the loadjava
command and everything seems to come up valid.
The stored procedure does a Class.forName() to get the driver
registered, than attempts to connect to the remote RMI driver.
The particular line it dies on is this (see the error below):
c = DriverManager.getConnection("jdbc:rmi:" + rmiHost + "/" + url);
A mangled version of this (minus the Oracle specific stuff) works
from the command line correctly. Can somebody point me in a
direction to figure out what's going on here?
THanks,
Eric

Performance problem with java stored procedure

hi,
i developped a java class, then I stored it in Oracle 8.1.7.
This class contains several import of other classes stored in the database.
It works, but the execution perfomances are disappointing. It's very long. I guess, that's because of the great number of classes to load that are necessary for my class execution.
I tried to increase the size of the java pool (I parameter 70 Mo in the java_pool_size parameter of the init.ora), but the performance is not much better.
Has anyone an idea to increase the performance of this execution of my class ?
In particular, is there a way to keep permanently in memory the java objects used by my class ?
Thanks in advance

before running Java, the database session needs to be Java enabled; this might be the reason why it is taking so long. If this is the case, you should see an improvement in subsequent calls, once a database session is Java enabled, other users can benefit from it.
Kuassi
I have some performance issue with java stored procedure. Hope some one will be able to help me out. I'm using java stored procedures in my application and basically these procedures are used to do some validation and form the XML message of the database tables. I have noticed that when I call the PL/SQL wrapper function, it is taking time to load the java class and once the class is loaded the execution is faster. Most of the time is spent for loading the class rather than executing the function. if I reduce the class load time, I can improve the performance drastically. Do any one of you know how to reduce the class load time. The following are the platform and oracle version.

How to retrieve 'long' column with 32K length in Java stored procedure

For some reasons, we are not using CLOB, BLOB, or BFILE to store large objects and I have to live with LONG. So I wrote a Java stored procedure to insert, select and manipulate a LONG column by retrieving the LONG into a java.lang.String class (which happens to be the Java class mapped to the LONG SQL datatype). It all works fine as long as the length of the value being retrieved is less than the magic figure of 32767 bytes (which is the restriction on LONG and VARCHAR2 datatype in PL/SQL as well). So looks like Oracle's implementation of the JVM limits String values to a max of 32767 bytes. Suggestions on how to overcome this limitation (other classes that you suggest or do I have to move to files)?
Thanks,
Jeet

the jvm has nothing to do with it ...
this is a pol/sql limitation on parameters in stored procedures.
and java stored procedures require a clal spec that makes the j-s-p look like a pl/qsl stored proc.

Issue with Oracle.sql.NUMBER in Java Stored Procedure

When we try to make a call to the Oracle.sql.NUMBER(String) inside a java stored procedure and pass values from '01' to '09', it throws java.lang.StringIndexOutOfBoundsException: String index out of range: 3
We use Oracle 9.2.0.6 - JServer Release 9.2.0.6.0.
It works fine for other values. Please find below the code used for simulating the issue outside the application. Thanks.
create or replace and compile java source named testNumber as
import oracle.sql.NUMBER;
import java.sql.SQLException;
public class TestNumber
       public static String convertNumber(String parm) {
                 NUMBER nTest;
                 try {
                         nTest = new NUMBER(parm);
                         return "TRUE";
                 }catch (SQLException sqle) {
                         return "FALSE";
create or replace function test_number (p_str in varchar2) return varchar2 as
language Java name 'TestNumber.convertNumber(java.lang.String) return
java.lang.String';
select test_number('05') from dual; - Throws exception ORA-29532: Java call terminated by uncaught Java exception: java.lang.StringIndexOutOfBoundsException: String index out of range: 3
select test_number('5') from dual; - Works fine
select test_number('010') from dual; - Works fine

Siva,
I'm only guessing, but it could be an Oracle bug, in which case I suggest checking with Oracle Support.
(You do have a support contract, don't you? ;-)
Did you try compiling and running your java class "TestNumber" outside the database?
Class "oracle.sql.NUMBER" should be in Oracle's JDBC driver, I believe.
Good Luck,
Avi.

Invoking Unix command with java stored procedure

Hi,
I have a perfectly working environment and now I am trying to replicate the same in another server. I have a java stored procedure which invokes the Unix command using java Runtime.exec() in my code named "run". I am sure that the code is called and the java class run is resolved in oracle as I could see that in dba_java_resolvers dictionary. But I am not sure whether the function in java is called or whether a exception is thrown. how to identify this? Could there be any thing to do with settings in oracle side? please help me.
Thanks in advance,
Marutha

Hi,
Do you get any output while running the code?
I'm testing similar solution and if there are any errors or Oracle can't execute the program due to permissions or other issues the error information will be displayed. Also in the Java class itself you need to catch exceptions and print stack trace to standard output.
declare
x number;
begin
dbms_output.enable(1000000);
dbms_java.set_output(1000000);
x:=system_command.run_command('testconnect.sh');
dbms_output.put_line('Returned value='||x);
exception
when others then dbms_output.put_line('Sql error='||substr(sqlerrm,1,250));
end;
<system_command.run_command> - replace with a call to your java stored procedure.

Issue with XSL transformation in Java Stored Procedure

Hi,
Am having issue applying XSL transformation in Java Stored procedure. I have loaded the java class as well as .XSL files through loadjava uility and their status in DB is VALID.
Below is the code in the java stored procedure:
public static String tranform(String strInputXML ){
URL url = ClassLoader.getSystemClassLoader().getResource(first.xsl);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new ByteArrayInputStream (strInputXML.getBytes("UTF-8")));
TransformerFactory tFactory = TransformerFactory.newInstance();
StreamSource stylesource = new StreamSource(url.openStream());
Transformer transformer = tFactory.newTransformer(stylesource);
When I run this procedure, am getting following errors:
{color:#ff0000}*ERROR: 'No such file or directory'*
FATAL ERROR: 'Could not compile stylesheet'{color}
My first.xsl file has reference to other excel file (Ex: <xsl:include href="second.xsl"/>) which seems to be causing this error. When I remove the reference, procedure is working fine.
Pls let me know how to resolve this and read the .XSL file with references.
Thanks,

Hello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks
